The active holder cradle charges your BlackBerry 9000 battery when it is in the holder. You need to connect the charging device to the 9000 BlackBerry device manually each time you put the device in the holder. The holder is attached onto a tilt swivel and can be adjusted in order to avoid light reflection. Connects to the vehicle's cigarette lighter socket, 12/24 Volt. Attach onto a ProClip Mounting Platform.
